After spending the first two weeks of the year on the disabled list Chase Headley returned to play 141 of the Padres’ final 148 games, but now that the season is over Marty Caswell of 1090-AM in San Diego reports that he underwent arthroscopic left knee surgery.

Last season Headley led the NL in RBIs and finished fifth in the MVP voting, but he hit just .250 with 13 homers and 50 RBIs in 600 plate appearances this season, seeing his OPS drop from .875 to .747. Headley has now played six full seasons and never come within 100 points of last year’s career-best OPS, so for now at least his 2012 looks like an aberration.

This time last year there was talk of the Padres possibly trading Headley for a big return and speculation about him breaking the bank as a free agent eventually, but now he’s heading into his final season under contract at age 30 with a lot of question marks. He hit 31 homers in 2012 and has hit a grand total of 49 homers in his other 670 career games.

Nava began the season on a one-year contract with the Angels, during which he slashed .235/.309/.303 through 136 PA in the first half of 2016. He was flipped to the Royals in late August for a player to be named later and saw the remainder of his year go down the drain on an .091 average through 12 PA in Anaheim. After getting the boot from the Angels’ 40-man roster in November, the 33-year-old outfielder elected free agency.

Nava is expected to compete for a bench role on the Phillies’ roster in the spring. As it currently stands, the club’s projected 2017 outfield features Howie Kendrick and Odubel Herrera, with precious little depth behind them. Nava’s bat is underwhelming, but at the very least he offers the Phillies a warm body in left field and a potential platoon partner for one of their younger options, a la Tyler Goeddel or Roman Quinn.

Former Mets catcher Johnny Monell signed a contract with the KT Wiz of the Korea Baseball Organization, per a report by Chris Cotillo of SB Nation. The 30-year-old originally struck a deal with the NC Dinos on Thursday, but the deal appeared to fall through at the last minute, according to Cotillo’s unnamed source.

Monell last surfaced for the Mets during their 2015 run, batting a dismal .167/.231/.208 with two extra bases in 52 PA before the club DFA’d him to clear space for Bartolo Colon. While he’s had difficulty sticking at the major league level, he’s found a higher degree of success in the minor league circuit and holds a career .271 average over a decade of minor league play. He played exclusively in Triple-A Las Vegas during the 2016 season, slashing .276/.336/.470 with 19 home runs and a career-high 75 RBI in 461 PA.

The veteran backstop appears to be the second MLB player to join the KT Wiz roster this offseason, as right-hander Donn Roach also signed with the club last month on a one-year, $850,000 deal.
